I am using CCM 4.1(3) with 600 users. Ordere by highest priority is Subscriber and then Publisher.
Today, I have rebooted subscriber server in one of the issues. When I rebooted subscriber, all active calls were down and then phones automatically registered with publisher in few seconds. After that I am able to make calls. I expected phones should register with publisher without going active calls down.
When subscriber is up, active calls were again down (as connected to publisher) and phones were registered with Subscriber.
Could you please help where it went wrong? I am expecting active calls should not be impacted when switch-over is happening between Subscriber and publisher.
